Question

please solve this problem ​

Answer 1

Answer:

cos(A-B) = √3/2. and sin(A+B) = √3/2

we know

cos30 = √3/2. and sin60 = √3/2

so,

A-B = 30 ....(1) and A+B = 60 ....(2)

add both the equations

we get

2A = 90

A = 45. and put this in any of the equations

we get B = 15

so A = 45 and B = 15

hope this will help you
